You’ve already met the cast who have become a veritable who’s who of comedy (Jason Segel, Seth Rogen, Amy Poehler), drama (Charlie Hunnam) and music (Loudon Wainwright). But working with Judd Apatow was a huge draw (especially after the critical acclaim of Freaks and Geeks) and a lot of big stars were willing to put in some time as guest stars or cameos on “Undeclared.” Even Freaks and Geeks stars like Samm Levine were willing to stop by the set. But cameos were also handed out to people who were still unknown but destined to become television stars. People like Tom Welling who is Clark Kent and Superman on “Smallville” and Mike White best known for “Chuck & Buck” and “The Amazing Race 14″ all showed their pretty faces on campus.
